compose: delete empty headers

When [compose].edit-headers=true and emptying a header in the text
editor (not deleting it, only deleting its contents), the operation is
ignored and the header is preserved as-is.

Delete the header after exiting the text editor if the header is empty
or not present. Make sure not to add empty headers.
